I2C to SPI bridge for AD7176-2

I am currently working on a DAQ system where it would be preferable to use an I2C interface for the AD7176-2 (so that it can be treated as a slave on the I2C bus).

I have seen several ICs which act as bridges between I2C and SPI (i.e. SC18IS602) however I'm concerned about the compatibility of these with the SPI implementation on the ADC, in particular due to the DOUT pin also behaving as an interrupt when a sample is ready.

Does anyone know of a suitable I2C to SPI bridging IC that will work with the given SPI implementation?

We do not have any precision sigma delta converters that use an I2C interface. I am not familiar with the chip that you refer to. The DOUT/RDT pin or bit does need to be monitored to determine when a conversion is available. The pin could be tied to a general purpose input pin of the uC and monitored periodically rather than connecting the pin to an interrupt.
